Connecting to a power supply

Recording loops

The C31 is equipped with two recording loops, for use with recording devices (such as cassette decks, MiniDisc players, VCR’s etc.)

7 TAPE/PROC RECORD OUT – Connect these output sockets to the input sockets of your recording device (usually labelled RECORD or IN).

8 TAPE/PROC PLAY IN – Connect the output sockets of your recording device (usually labelled PLAY or OUT) to these inputs.

If you do not have a recording device, you can use this input for other (line-level) equipment, such as a CD-player, tuner, VCR, etc.

9 VCR/TAPE2 RECORD OUT – These output sockets can be connected to the input sockets of a second recording device.

bk VCR/TAPE2 PLAY IN – Connect the output sockets of your second recording device to these inputs. Alternatively, this input may be used for other (line-level) equipment such as a CD-player, tuner, etc.

Power-amplifier connections

456 PRE OUT – The recommended connection between the C31 pre-amplifier and your power amplifier depends on both the distance between the two and the type of power amplifier that you are using. There are three options:

1.If the cables to be used to connect the C31 to the power amplifier are less than 3m long, we

recommend connecting the DIRECT sockets 6 to the input sockets of your power amplifier. On the P35 and P1, connect to the socket(s) labelled AUDIO IN.

If the cables to be used to connect the C31 to the power amplifier are 3m or longer, then the connection to use depends on the type of power amplifier you have.

2.If your power amplifier does not have balanced inputs (such as the P35), use the BUFFERED outputs 5. On the P35, connect to the sockets labelled AUDIO IN.

3.If your power amplifier provides balanced inputs (such as the P1), use the balanced outputs 4. On the P1, connect to the sockets labelled BALANCED AUDIO IN.

The buffered and balanced outputs are designed to drive longer cables than the direct output, but you cannot damage either your C31 or your power amp. by using the “wrong” connection type.

Other connections

Phono earth terminal – For connecting your turntable earth lead (if required). Note that this terminal must not be used as a safety earth.

3 TRIG OUT and REMOTE IN (12V in and out) – These connections are intended for use in multi- room installations.

<TRIG OUT: This output provides a 12V signal whenever the unit is switched on (i.e., not off or in stand-by). This signal can be used to switch on power amplifiers (or other equipment) connected to the C31, as they will come on when the C31 is activated. This is useful if the power amplifier is remote from the C31, or otherwise difficult to access.

<REMOTE IN: This allows remote-control signals to be received by the C31 if the remote sensor is covered (or otherwise not ‘visible’ to the remote-control). An external sensor (such as the Xantech ‘Dinky Link’™) is used to receive the signals from the remote-control, which are then fed to the C31 (into this input) using a suitable cable.

In normal use there is no need to make any connections to either of these sockets.

Mains lead

The appliance is normally supplied with a moulded mains plug already fitted to the lead. Check that the plug fits your supply and that your mains supply voltage agrees with the voltage setting (115V or 230V) indicated on the rear panel of the unit 2 before plugging in.

If your mains supply voltage or mains plug is different, please consult your Arcam dealer immediately.

Plugging in

Push the IEC-plug of the power cable into the socket POWER INLET 1 in the back of the unit, making sure it is pushed in firmly.

The 12V-trigger uses a 3.5mm mono jack plug, wired as follows:

<Sleeve: Ground

<Tip: Active When the C31 is powered-on, the tip carries 12V, current- limited to 30mA; other- wise the tip carries 0V.

The remote-in also uses a 3.5mm mono jack plug, wired as above. Remote control signals must be in modulated RC5 format, with a voltage level of 5–15V. Note that the remote receiver will require its own power-supply.

Details of the Xantech ‘Dinky Link’ can be found at www.xantech.com, or ask your dealer.

Stand-by power

For remote stand-by operation, the amplifier’s control power-supply is kept powered up all the time the unit is connected to the mains supply. The front-panel power-switch powers all other circuitry down and power consumption in this mode is less than 2W.

This means that even though the power-switch is off, it may be possible to hear a slight residual hum coming from the mains transformer inside the amplifier. This is perfectly normal. If the unit is to be left unused for an extended period, however, we recommend that it is disconnected from the mains supply.
